What is the difference between Waxoyl and Dinitrol?


DINITROL is a wax which dries to leave a cured soft outer layer where as Waxoyl is a mixture of wax and oil which never cures and continues to be liquid even after many months. Waxoyl is only one product to treat the whole of your vehicle, Dinitrol is made up of four different products which are specifically designed for each section and cavity of your vehicle.
